When using the Huawei E5577 you are in essence connecting to the mobile data network in exactly the same way as your phone. If you don’t have a phone data signal then unfortunately you wont have a WIFI signal. So a top tip is to ensure your sim card is on a separate network provider to your phone to make sure you have the best opportunity to have a data network signal. I have made the mistake in the past of having both my phone and MiFi device on the same provider network meaning if I couldn’t get a signal on one then I definitely couldn’t get one on the other. Pricing The Huawei E5577Cs-321 is a router that offers reliable and secure wireless connectivity. Built by Huawei, a leading telecommunications company, this router is designed to provide consistent and fast internet access. The router also offers secure wireless encryption protocols, such as WPA2-PSK, to protect users' personal information and keep their internet connection safe from unauthorized access. Before powering up the device, you need to make sure that you have network coverage for the SIM in the area you’ll be using it. It takes about 30 seconds for the Huawei E5577C to boot up and connect to the network. After the welcome screen, the network information is shown on the screen. If your mobile provider doesn’t offer coverage then you could always swap the sim in your phone for another provider who does offer coverage, but I guess not many people will want to do this. So using a MiFi device like the Huawei E5577C will make it simpler to swap sim cards. Like me, you could buy an EE PAYG data sim (EE currently offer the best UK 4G coverage) or find out who offers the best coverage in the area you’re staying in, and buy that mobile provider’s data sim.

However, if your phone’s network coverage is poor (or not supposed to be available in the area, like I found with EE), then using a MiFi device like the Huawei E5577C connected to a good external antenna like the Poynting XPOL-A0001, can provide great results. Even with a poor signal, using the Huawei E5577C with the XPOL-A0001 antenna gave some impressive 4G broadband speeds. Network providers… Tip: If you’re using a laptop in your campervan to connect to the internet, turn off automatic updates. Or you could waste most of your data allowance on updating your operating system! Maximum size for each attachment is 10MB (rar, jpg, zip, pdf, war, txt, docx, doc, png, mp3, mp4, xls, xlsx, gif, jpeg are supported). LTE: 150 Mbit/s down, 50Mbit/s up * UMTS: 42.2 Mbit/s down, 5.76 Mbit/s up (when using DC-HSPA+) * GSM: 384 kbit/s (when using EDGE ) Huawei E5577C supports LTE by category 4 with up to 150 MBit/s in the downlink and 50 Mbit/s in the uplink. Actually, LTE Cat4 is not the latest new technology. Here now there is LTE Category 6 mobile hotspot Huawei E5786 available. But new technology means user need pay more money to enjoy it. For most users, the LTE Cat4 modem in E5577C will provide sufficient speeds and in testing, it can achieve top speeds of up to 140 Mbit/s. In the UMTS network the data accelerator DC-HSPA+ is of course supported, so here theoretically up to 42.2 Mbit/s can be achieved in the downlink. In practice, you should reach the speed of no more than 32 Mbit/s.

Il est pénible de commander un produit dont la photo et la description impliquent la possibilité d'utiliser une antenne extérieure Mimo (2 x SMA). In the web interface, there are detailed statistics on the internet, you can send and receive SMS and you can share files and folders on the network when inserted MicroSD memory card. There is also a menu item to update the firmware. In the settings menu, there are several configuration options available for WLAN and network. Overall, the web interface of the E5577C is quite extensive and easy to operate! Once you’ve successfully connected to the WIFI network you should then see ‘Wi-Fi’ (as opposed to 2G, 3G or 4G) and the networks SSID on the home screen. This reveals the battery compartment, full-size SIM card slot and microSD card slot. Inserting a microSD card (optional) enables the user to store and share data on the card.

Die Konfiguration, also wenn ich mich über die IP Adresse in den Router einlogge, ist nicht ganz so einfach weil die Chinesen sich bei der Übersetzung ins Deutsche nicht wirklich viel Mühe geben und dann ist schon etwas Fantasie angesagt. Equipped with a powerful battery, this router can provide continuous usage for hours without needing to be charged. This ensures that users can stay connected even without access to a power source for an extended period of time. Unfortunately, there is no way for the Huawei E5577C set to a specific network technology. The only option is the use of LTE-on and to turn off. Compared to several other mobile hotspots, this is a big disadvantage. A Mifi or portable mobile hotspot is a device that works much like a smartphone. You insert a sim card into the MiFi device and it connects to a nearby 4G network. If there’s no 4G then it will automatically switch to 3G. Now in itself, the MiFi unit is no different from a smartphone in that respect, however, the real benefit comes from connecting an external antenna to the MiFi device.

In the picture below, you can see one cable adaptor screwed into one of the XPOL-A0001 antenna’s cables. While the E5577C does not offer as many features as some other routers on the market, it provides a basic solution for those in need of wireless internet access while on the move. Its simplicity and ease of use make it suitable for casual users or those who require a temporary internet connection. I don't know about battery life (others have said 4-6 hours) as I use the supplied mains-USB adapter and supplied USB cable, and leave it as mains-powered.
